Is unbromated flour kosher for passover?

Unbromated flour is not kosher for Passover because it may contain chametz, which is any food made from wheat, barley, rye, oats, or spelt. These grains are forbidden during Passover because they are believed to have caused the Israelites to suffer in slavery in Egypt.

Bromated flour is made with potassium bromate, a chemical that helps to strengthen the flour and make it more elastic. Bromated flour is not permitted for use during Passover because it is considered to be a kitniyot, which is a type of food that is not specifically forbidden by the Torah but is still avoided during Passover.

There are some brands of unbromated flour that are certified as kosher for Passover, but it is important to check the label carefully before purchasing.
